Milling Steel on DMG Mori HSC55 in Munich, DE


Comparison of cycle time and the surface quality.
Standard Spindle v. Air Turbine Spindles® - 50% time reduction

Test Parameters:
Linear Milling Depth: Row depth 2.0-0.13 RA
Material: 1.2344 Steel – HSC 30/70
Tool: Ball nose end mill R 2, 0.03mm/z

Cycle Times:
Standard DMG HSC 55 Spindle - 25,000 rpm
Advance: 1,500 mm/min = Cycle Time: 60 minutes

Air Turbine Spindles® 625HSK Spindle - 50,000 rpm
Advance: 3,000 mm/min = Cycle Time: 30 minutes.

Observations on Surface Finish:
The quality at Ra 0,13mµ and precision were indistinguishable between the 25,000 rpm DMG HSC 55 spindle in the top Image and the Air Turbine Spindles® governed 50,000 rpm 625HSK in the bottom image.

Any CNC becomes a high speed machine in minutes with Air Turbine Spindles®.

Load your Air Turbine Spindles® automatically from any CNC magazine in to your main spindle. Clean dry compressed air is induced through a clean airline, or an optional patented mounting block and collar, for seamless integration in your program. No manual hook up required unless preferred. Click Here to view video of autoloading.

1. Maintain constant high speed on the tool path at 25,000 to 90,000 rpm with power to 1.4hp (1kW) - You keep constant high rotational speed in angles and hard materials.

How? Air Turbine Spindles® patented governor increases airflow in the turbine in proportion to the load. Click Here to view 50 action videos.

2. Reliability, low vibration, low heat and no duty cycle for 24/7 milling.

Why? That’s because our direct drives have only 2 moving parts – our proprietary turbine and ceramic bearings, and the bearings are cooled by turbine airflow. No High frequency brushes, no gears to burn up, no control system. Click Here to view the product range.

Just connect to 90 psi / 6.2 Bar and high speed Air Turbine Spindles® and mill, drill and accelerate your feeds with no duty cycle. No control system or lubrication required.
